LOADING A?PARATUS.

Application filed September 27, 1924,

T all whom t may concer/n:

Be it known that I, GEORGE A. FLEBOTTE, a citizen of the United States, residing at Indian Orchard, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Loading Apparatus, of which the following is a specification.

This invention relates to improvements in loading apparatus for excavating purposes, as removing soil from road-ways, cellars and conveying the removed material into a truck for drawing the removed material away for grading or other purposes.

The invention, broadly, comprises an endless travelling conveyor member which is provided with soil engaging scrapers that will collect the soil and carry it upward onto a second endless travelling conveyor which, will in turn, convey it to the receiving receptacle or truck. The motive power for operating these conveyors is mounted on a separate trailer' or platform having a suitable motor, as a gasolene motor, which is belted to a train of gearing for operating the conveyor chains. Suitable devices are provided for folding the different members of the conveying apparatus into a compact position so that the platform trailer may be conveniently moved from one place to another for use. Other devices are further provided for varying the vertical elevational position of the endless conveyors which operate on the embankment or cellar for removing the earth material.

Referring to the drawings:

Fig. 1 is a side elevational view of the complete appara-tus showing it as used for excavating purposes and illustrating in d otted lines the method of folding one portion yonto the other in order that it may be moved from place to place by the supporting trailer.

Fig. 2 is a plan view of Fig. 1 illustrating the scraper bars attached to the endless chain conveyor, also the windlass construction for raising and lowering the scraper bars.

Fig. 3 is a detail view of a portion of the conveyor belt which receives the earth material that is carried upward by the scraper bars and delivered onto this endless conveyor.

Fig. 11 is a detail perspective view of one of the scraper bars showing an arrow to indicate the direction that the bar and its cha-in moves. e

Referring to the drawings in detail:

1 designates a wheel mounted platf rm for supporting the loading apparatus. It is mounted on supporting wheels 2 and designed to be propelled by means of the motor indicated at 3 which motor is connected through the gear box 4 to the usual propellor shaft Secured on the platform 1 are three uprights indicated at 6, 7 and 8. Mounted in the up-right 7 is a sprocket wheel 9 that is driven from the motor 8 by means of the sprocket chains 10 and 11. 12 designates a sprocket chain which connects the shaft of the sprocket wheel 9 to the sprocket wheel 13 whichflatter wheel drives the shaft 14: that carries a gear wheel 15 that meshes with the second gear wheel 16. The gear wheels 15 and 16. being of the same diameter will cause the rate of rotation of the gear wheel 16 to be equal to the rate of rotation of the gear 15. drives the sprocket wheel `1T over which passes aY sprocket chain 18. This chain engages a sprocket wheel 19 that is mounted on the transverse shaft 20. This shaft is supported in the bearing boxes 2l that are The gear 16 secured to the tip-right side. bars vhich consist of angle iron. The upper ends of these bars are rigidly connected together by the cross members 23 and near the upper' ends of the bars 22 is located the windliss 2l. which is secured to the operating shaft 25, one end of which is provided with an operating handle 26. Passing around the windlass 2l is a rope 2T, the lower end of which is attached to the outer ends et the frame work 28, which trame is made up or the bars 29 and 80. Rotatably mounted in the outer ends of the bars 29 and 3() is the sha't't- Sl, on the opposite ends of which are secured the sprocket wheels 32 and 33 over which passes the sprocket chains 34 and A detail or" one of the links is shown in Fig. G indicated by the reference numeral 36 and a detail oi"l one of the links which is' connected to the link 36 and to which the scraper bars 37 are attached is indicated at 38 which link is formed with an upwardly extending part 39 having the opening el). rlhe scraper bars 37 are riveted or otherwise secured to the links 3S with the rivets Ll-l. These bars are formed with the angular shaped ends 42, as shown in Fig. .7. The spocket chains 84 and 35 with the earth scraper bars 37 attached thereto travel in the direction of the arrows indicated at 3 and ed. The inner or discharge ends :tor the scraper bars is arranged over the endless conveyor belt l5 shown in the enlarged view in F ig. 9. This belt conveyor passes over the pulley 46 at one end and over a pulley 4.7 at its inner end. These two pulleys are rotatably mounted in the latticed 'frame work 48, (see Fig. l), which tram-e work is pivotally mounted in the 11p-right 5 and may be clamped in dierent vertical positions by means o't the device indicated at rJChe up-right 6 as shown is formed with a slot 50 'for `-arying the vertical position of the frame work 48. 5l is a driving belt for the belt conveyor 45 which passes over the pulley 52 which is secured to the same s'hat as the sprocket wheel 9. rlhis belt passes around a pulley el? which is mounted on the same shaft as the pull-ey l? over which passes the endless belt conveyor e5. A detail of this endless conveyor is shown in Fig. 55 are side strips to confine the material being conveyed to the truck, The delivery end of the co veyor 45 is located over the receiving truck 58 as indica-ted in Fig. l. The scraper bars 37 will engage the earth inaterial indicated at 54 and in turn will carry a portion ot' the removed material and deliv-er it directly onto the endless traveling conveyor 45 which discharges it into the truck as shown. The sides of the conveyor Ll5 are provided with metal plates 55 (see Fig. 3) to confine the material in the center portion oit' the same to prevent its working over the side edges thereof. The

latticed frame work sl-S has pivoted at its lower end the two tip-right bars 22, indicated at 56. Attached at 22 to the upper end otl the up-rio'ht t'rame work 22 is a supporting cable 5:', the other end of which cable is attached to the Ylranie work 4S at 48. Extending the side bars ot the Vtraine 28 is a rod 58. On the outer ends ot this rod is placed the. grooved pulleys S cured to the lower ends o'l' the rip-rights 22 are the two bars GO as indicated at (il. Located on these bars are the pulleys (S2. Also located on the Lip-rights 22 are the winding drums 63 which are operated by the cranks G4. Attached to the upper ends ot the bars GO are cables (E5 which pass around under the pulleys 62 to the winding drums G8. ln order to properly support the bars l5() braces G5 are provided which are secured to the bars 60 by rivets ill' and to the frame 48 by rivets GS.

lVhen it is desired to fold the apparatus tor transportation; the operator elevates the frame 2S by rotating the winding drum 24e. rifhis operation turns the traine 28 on its pryotal connection at 20. The arrow 69 indicates the path oi its upward movement. A continued rotation o't' the windlass or drunl 2l brings the pulleys 59 on the 'frame 28 against the cables G5 causing theirL to assume the looped position indicated by the dotted line of these cables at G5. The frame 28 is now hooked up or supported in this upright position by these cables. The next operation is to 'told the up-rights 22, and frame 28 onto the latticed frame LlS as indicated by the dotted line positions 22 and 28 and about the pivotal center 5G. Next tl e operator folds or tilts the frames L18, 2S and 22 as a unit about its pivotal support 7 in the upright 7. 69 indicates a support or rest for this unit at its forward end on the rip-right S. The whole is now secured in place by the tightening nut 49 with the arm 70. In order to untold the. apparatus the operations are of course reversed. The windingl ol1 the cables which supports the trame 28 in an upward position onto the drums (3-3 will shorten the same and cause the pulleys 5S) to operate to force the frame 28 to return to its original position. The cable 27 is now unwound from the drum 241; permitting` the frame. 2S to be lowered ready t'oi' operation again. The frame 2S is raised and lowered by operating the drum 2t so that it may be adjusted and held properly in working' position.
